Price Feed Lag

Definition

Price feed lag represents the temporal disparity between the arrival of real-time market data at an exchange and the corresponding update within a smart contract or derivatives pricing engine. This phenomenon occurs when network congestion, oracle latency, or computational bottlenecks delay the propagation of spot prices. For traders, this misalignment creates a vulnerability where execution occurs against stale valuations, often resulting in unfavorable trade fills or premature liquidation events.
